[. . . ] Attention should be paid to the location and installation of the various antennas, in order to support the antenna characteristics in the best possible way. VHF Antenna Installation Antenna Location Location of the mandatory AIS VHF-antenna should be carefully considered. Digital communication is more sensitive than analogue/voice communication to interference created by reflections caused by obstructions such as masts and booms. It may be necessary to relocate the VHF radiotelephone antenna to minimize interference effects. To minimise interference effects, the following guidelines apply: · · The AIS VHF antenna should have omni directional vertical polarisation providing 3 to 5 dB gain. The AIS VHF antenna should be placed in an elevated position, as free standing as possible, with a minimum of 2 metres in horizontal direction from constructions made of conductive materials. The antenna should not be installed close to any large vertical obstruction. The AIS VHF antenna should have a visible sky of 360°. The AIS VHF antenna should be installed at least 3 meters away from interfering highpower energy sources such as radar and other transmitting radio antennas, and out of the way of the transmitting beam. There should not be more than one antenna on each level. The AIS VHF antenna should be mounted directly above or below the ship's primary VHF radiotelephone antenna, with no horizontal separation and a minimum of 2 metres vertical separation. If it is located on the same level as other antennas, the distance apart should measure at least 10 metres. See also sample for antenna layout in Appendix 9. 2 (Drawings and Approvals) · · · Cabling The cable should be kept as short as possible to minimise attenuation of the signal. Double shielded coaxial cables equal to or better than RG214 are recommended. RG214 at VHF attenuation per meter of app. 0, 07 dB/m (45m = 3, 15db) VHF AIS frequency app. 162MHz GlobalWatchTM UAIS Installation Manual 17 Y1-03-0177A Version 1. 0 All outdoor connectors on the coaxial cables should be fitted with preventive isolation, such as shrink-stocking with silicone to protect the antenna cable against water penetration. Coaxial cables should be installed in separate signal cable channels/tubes, and at least 10 cm away from any power supply cables. Crossing of cables should take place at right angles (90°). Coaxial cables should not be exposed to sharp bends, which may lead to changes to the characteristic impedance of the cable. The minimum bend radius should be 5 times the cables outside diameter. Grounding Coaxial down-leads must be used for all receiving antennas, and the coaxial screen should be connected to the ground at one end.
